Relation in Django REST Framework? - django

Question

I am using serializers.GeoFeatureModelSerializer to serialize Model. I have a queryset
that is creating Left Outer Join. I want to serialize related Model fields
Here is my Model
class LookupTiming(models.Model):
day = models.CharField(max_length=7)
time_1 = models.TimeField()
time_2 = models.TimeField()
class Meta:
db_table = u'lookup_timing'
class Streets(models.Model):
name = models.CharField(max_length=50)
geometry = models.GeometryField(null=True, blank=True)
objects = models.GeoManager()
class Meta:
db_table = u'streets'
def __unicode__(self):
return '%s' % self.name
class StreetTimings(models.Model):
street= models.ForeignKey(Streets)
lookuptiming = models.ForeignKey(LookupTiming)
class Meta:
db_table = u'street_timings'
queryset =
Streets.objects.filter(streettimings_lookuptiming_isnull=True)
Serializer Class
class StreetSerializer(gis_serializer.GeoFeatureModelSerializer):
class Meta:
model = Streets
geo_field = "geometry"
id_field = False
fields = ('id', 'streettimings__lookuptiming__day', other fields)
Updated
I want to show following fields on response
Streets (id)
LookupTiming (day)
I want output like this query simple is that
SELECT "streets"."id", "lookuptiming"."day" FROM "streets"
LEFT OUTER JOIN "streettimings" ON ( "streets"."id" = "streettimings"."street_id" )
LEFT OUTER JOIN "lookuptiming" ON ( "streettimings"."lookuptiming_id" = "lookuptiming"."id" )
How can i do this?
Thank you
